Need some assistance ASAP pleeeze...

Is the Superman ROS at SFNE the same exact coaster (layout, etc.) as the one at Darien Lake? I'm headed to both parks & thought if it'd save time at either park to skip one or the other Superman coaster. Also, is this coaster smooth or jerky; ie: which seat gives me the least jerky ride on either or is it a generally smooth coaster like Steel EEL, etc? Thanx, in advance, to anyone who replies.
